This fixes two bugs on linux: `/tmp` and `$HOME` are technically on two different partitions on my machine, which means that rename-as-atomic-dir-write doesn't work. The solution is to create the temp dir in the target directory. zip files may contain directory entries, we can't create files for them but need to create directories. We could skip them though because iirc they are not in the RECORD so they won't be uninstalled.
